Complete and partial oil change in an Audi A6 C5 automatic transmission. Instructions for changing the automatic transmission oil in an Audi A6 yourself. What kind of oil is in the A6 automatic transmission?

An automatic transmission is a complex system that requires careful attention during operation. Any car owner is obliged to systematically update the transmission fluid, since high-quality oil is considered the key to long-term and reliable operation of the gearbox.

A5 are very similar and do not present much difficulty. The fluid change can be either complete or incomplete. It is worth mentioning that a complete change of the lubricant mixture in the Audi A6 automatic transmission is considered the most effective procedure and it is sufficient to carry it out every 50 thousand kilometers. Partial replacement is recommended to be carried out much more often - approximately every 15 thousand kilometers.

Since a complete change is possible only under special conditions with the connection of special equipment, in this article we will consider only a partial replacement of gear lubricant.

What kind of lubricant and how much is needed?

For a partial change of ATP, 5 liters are enough, for a complete change you will need a little more. According to reviews from car owners, ESSO LT 71 141 oil is recommended for the A5. Esso ATF LT 71141 is a high-quality transmission lubricant. This product is created on the basis of the best oils and a high-quality set of additives, which guarantees excellent performance data and makes it possible to extend the fluid change time. Following the merger of ESSO and Mobil, Esso ATF LT 71141 is now called Mobil ATF LT 71141.

Video “Changing ATF to Audio”

After watching this video, you can figure out how to independently change the transmission fluid in the Automatic Transmission Audio A6 and A5

The Audi A6 is an excellent purchase for fans of high-speed driving. The machine is equipped with engines that guarantee optimal power and acceleration. There are cars that run on gasoline or diesel fuel and have a manual or automatic transmission.

The need to change transmission oil

The transmission level should be checked every 15,000 km. The fluid changes completely during TO-3 or TO-4. What tools are needed? To replace fuel in the gearbox, you need an empty container, rags, a filling syringe, and wrenches. Also, it is necessary to replace the pan gasket and use a cleaner.

Position of the filler and drain holes on the gearbox

Changing the oil in the automatic transmission of the Audi A6 C5 takes place in a number of stages. Let's list them:

1. The car is placed on the inspection hole (the engine must be warmed up).
2. Removing the pan from the gearbox.
3. The drain plug is unscrewed to allow the liquid to drain into the substituted container.
4. The pan and plugs should be washed with cleaner.
5. The magnet that needs to be cleaned is built into the plug.
6. The cleaned parts are installed in place.
7. Fuel is filled using a filling syringe.
8. The engine starts, the gears are changed several times, after which the oil poured into the system is checked.
9. Finally, the oil is drained and new oil is added.

This process requires approximately 5.5 - 6 liters of oil.

After using the machine for several days, you need to check again how much oil has decreased. If necessary, it should be topped up to the optimal level. The oil filter and pan gasket are changed along with the oil. All these activities, including changing the automatic transmission oil on an Audi A6, can be done with your own hands.

How to check the oil level in an automatic transmission? It seems possible to measure the transmission fluid level using a dipstick. This item has divisions on the readings of which you can accurately determine the liquid level (it should be higher than the first two divisions). Of course, the check should be carried out with a warm engine; the foreign car is started on an overpass.

Which oil to choose?

For Audi A6 (C5) cars, transmission fluid should be used from the following manufacturers:

• Esso;
• Mobil;
• Shell.

Mobil Esso Shell M-1375.4

The driver can independently determine what class of oil is poured into the automatic transmission of the Audi A6. Especially for this, you should provide yourself with access to the high-speed gearbox, where there is an identification number on the nameplate.

An urgent need to replace the fluid is required if it has darkened or acquired a burnt smell. This will minimize the risk of wear and tear on the vehicle system.

Thus, in order to increase the service life of the automatic transmission on an Audi (C5, C6), you should select and use high-quality fuel. A complete oil change is carried out at 50,000 km.

The service life of the power plant and transmission of vehicles depends on compliance with the frequency of maintenance. This applies to all cars, including business class models, which include the Audi A6 C5.

Although this model has not been produced since 2005, it is quite popular and is owned by many car enthusiasts.

The main maintenance operation for the Audi A6 C5 is the replacement of technical fluids in units and components, primarily the engine and gearbox.

At the same time, the manufacturer produced many modifications of this car with different types of power plants and 3 different gearboxes - manual, automatic transmission and CVT (Multitronic), which influences the methodology for carrying out maintenance work.

Despite the significant number of engine types, the technology for changing engine oil in them is generally identical, which cannot be said about the gearbox. Each transmission option has its own characteristics and nuances of performing the work.

Replacing technical fluids in the power unit and transmission should be carried out by technical service specialists, but these operations are not particularly complicated and everything can be done independently, saving on service station services.

Changing the oil in the power plant

Changing the oil in an Audi A6 C5 engine is not a complicated operation, but the technical fluid in power plants changes much more often than in other components. It is recommended to carry out this operation every 5-10 thousand kilometers (depending on the operating conditions of the car), or once a year.

Materials and equipment

As a replacement, you should purchase synthetic oils from well-known manufacturers - Castrol, Liqui Moly, Statouil Lazerway, Motul with a viscosity of 5W-30, 5W-40 and A3/B4 approval.

As already noted, the algorithm for changing engine oil is almost the same for all cars, only the amount of material to be filled differs.

For example, consider the sequence of work in the 2.8-liter Audi A6 C5 gasoline engine.

To complete the work you will need:

• Motor oil (6 liters);
• Oil filter;
• Container for collecting waste;
• Key to 19;
• Screwdrivers;
• Filter puller;
• Rags.

You will also need an inspection hole or overpass. You can do without a pit, but you will have to find either a small, but wide container, or build a structure from plastic bottles.

Having prepared everything, you can start working.

Work technology

The replacement should be carried out on a warm engine, not a hot one, so as not to get burned when draining the waste.

Work algorithm:

After replacement, we inspect the drain plug and filter for leaks (if necessary, tighten them) and replace the crankcase protection.

Resetting the meter

In addition to changing the engine oil, you should reset the maintenance frequency counter (Service Oil).

This is done like this:

• Press and hold the daily mileage reset button (with the ignition off);
  
• Turn on the ignition (holding the key) until the inscription “Service Oil” appears on the on-board computer display;
  
• Release the mileage key, pull the clock setting key towards you and hold it until the “Service Oil” inscription on the display is replaced by the marks “—”, release the key;
  
• Press and hold the run key again until “Service INSP” appears;
  
• Again we pull the clock setting key towards ourselves, after which the inscription should be replaced by the same marks “—”;
  
• Turn off the ignition.

Through such manipulations, the counter is reset, and it will again begin counting the mileage until the next maintenance from scratch.

Changing the automatic transmission oil

Three types of gearboxes were installed on the Audi A6 C5, and each of them has its own frequency of replacing technical fluid and technology of work.

Methods for performing replacement

First, let's look at the replacement method for an automatic transmission. Let us immediately note that for this type of gearbox there are two replacement methods - partial and complete.

Partial replacement must be performed every 50-60 thousand kilometers. This method can be done independently, but it is not recommended to use it alone all the time.

A complete replacement is carried out after 150 thousand km and is done using specialized equipment in a car service center.

The amount of lubricant depends on the replacement option. With a partial change, 6 liters of oil are usually consumed, and with a full change - 10-12.

Materials, equipment

To replace, you will need special oil for automatic transmissions. For Audi A6 C5, you should purchase original SWAG lubricant with catalog number 30914738 or analogues - Mobil ATF LT1141 or Liqui Moly ATF Toptec 1200.

Let's consider the algorithm for partially replacing the lubricant in an automatic transmission. To carry it out you will need:

• ATF oil (6 liters);
• Pan gasket;
• Oil filter;
• Replacement drain and filler plugs;
• Set of sockets, hexagons and Torx;
• Technical syringe;
• Torque wrench;
• Container for collecting waste;
• Rags.

Algorithm of actions

The work is carried out on an inspection pit or overpass. The technology is as follows:

• We unscrew the drain plug from the automatic transmission pan using a 8mm hexagon, having previously placed a container under it;
  
• We wait until the lubricant has completely drained (about 5 liters), after which we put the plug in place and tighten it with a force of 40 Nm;
• Using Torx T27, unscrew the fasteners of the pallet and remove it along with the gasket;
  
• Drain the remaining oil from the pan into a waste container;
  
• Based on the condition of the oil and the presence of chips on the magnets installed on the pan, we determine the condition of the automatic transmission (dark oil with a pronounced burning smell, as well as a large amount of chips will indicate severe wear of the transmission elements and the need for repairs);
  
• Thoroughly clean and wipe the tray and magnets;
  
• We unscrew the screws securing the filter and put a new element in its place (if there is no new one, you can try to wash the “old” one and use it again);
  
• After replacing the filter, put the pan back in place, replacing the gasket on it. The pallet fasteners should be tightened to 10 Nm. The tightening procedure is shown below;
  
• Using a 17mm socket, unscrew the filler plug (installed on a tray near the drain plug);
  
• We pump new oil through the hole in the filler plug using a technical syringe with a curved tip or a rubber nozzle, a pump, etc. (a plastic sleeve is placed on the hole from inside the pan, which will prevent the oil from spilling out). In this case, in order to fill the lubricant, the tip of the injection device should be placed behind this sleeve;
  
• Fill until lubricant begins to drip from the hole;
  
• Tighten the filler plug (tightening torque – 80 Nm).

After the replacement procedure, we start the engine and use the gearbox selector to go through all the operating modes of the box.

After warming up the box to 45 degrees, we check the lubricant level in it. To do this, unscrew the filler plug again (with the engine running).

The level is considered normal when small droplets of lubricant fly out of the hole. If they are not there, add more oil (with the engine running) until it flows from the hole, then tighten the plug. At this point, the partial replacement can be considered complete.

Manual transmission

The Audi A6 C5 was also equipped with a manual gearbox. The manufacturer indicates that the lubricant life in such a gearbox is designed for the entire period of operation of the vehicle.

Therefore, changing the oil in such a box is considered only a preventative measure and it is not necessary to perform this operation. Still, it is recommended to carry out the procedure once every 2-3 years.

Equipment, materials

As a replacement for such a gearbox, you should purchase synthetic gear oil with a viscosity of 75W-90 standard G4. You can buy it as an original lubricant - VAG with catalog number G-052911-A2 or analogues - Liqui Moly, Castrol, Mobil, with the appropriate viscosity and standard. At this point, the operation of replacing the lubricant in the Audi A6 C5 manual transmission can be considered complete.

Replacement in the variator

Another box that was equipped with the Audi A6 C5 is a CVT (Multitronic). This type of gearbox, like an automatic transmission, is quite sensitive to the quality and quantity of oil, so it needs to be replaced every 60 thousand km.

Materials, equipment

Another feature of the variator is the lubricant itself. Only original VAG oil marked G-052180-A2 must be filled into this box; this lubricant has no analogues.

"Washing" the box

The washing technology is as follows:

1. We hang the car on a lift;
2. We start the power plant;
3. In manual gear shift mode (Tiptronic), we shift the speeds up, starting from 1st and accelerating a little (according to the tachometer or speedometer), but do not exceed the speed of more than 50 km/h;
4. We repeat the procedure in reverse order (switching gears from higher to lower);
5. We stop the rotation of the wheels with the brakes;
6. Set the selector to “R” mode and pick up speed on the speedometer to 20 km/h;
7. We stop the wheels and repeat the procedure, but in mode “D”;
8. We perform points 5-7 5 times.

Lubricant replacement

After “flushing” and cooling the variator, we perform the oil change itself.

This operation is done like this:

After this procedure, all that remains is to check the lubricant level and add it if necessary. The test is carried out at a box temperature of 30-35 degrees. WITH.

After reading a topic of almost 90 pages, I realized how many people spend a lot of precious time choosing 10% of useful information among this garbage, such as: “What should I put in my multitronic?”, “Do I have a CVT or an automatic?”, “My VIN: XXXXXXXX, where should we run???".
In general, I wanted to summarize a little information so that all this would be more accessible.

Our wonderful car manufacturer Audi (read both BMW and MB...), having opened its pocket wider, or maybe simply not giving a damn, has included in the routine maintenance work on the cars it produces, or rather on the fluids of their hydromechanical automatic transmissions, a maintenance period - “for the entire service life” however, from the ZF regulations it becomes clear that where is the catch?
It is obvious that any fluid for automatic transmissions is subject to aging; the properties that it must have for correct operation are lost under the influence of load and temperature. Audi, as a car manufacturer and a guarantor of reliability (for a certain period!), apparently, is of little concern about this, since due to the “aging” of automatic transmission fluids, the latter do not break down until 100,000 km, but only begin to undergo greater wear. But the automatic transmission manufacturer ZF, which supplies units for the Audi assembly line, apparently caring about its reputation, may still be worried about the wear resistance of transmissions. These arguments can be confirmed not only by the ZF regulations, but also, in turn, by Audi’s concern about multitronics that fail without a long fluid change (replacement according to the regulations at 60,000 km), warranty replacements of which would cost a lot of money.
If you are motivated enough and think that you need to change the automatic transmission fluid, there are still pitfalls.

In general, there are several options when approaching the issue of replacing fluid in a 6HP19 automatic transmission on all-wheel drive versions of the Audi A6 4FC6.

To change or not to change?

1. If you want to change the fluid in the automatic transmission in the presence of obvious malfunctions, such as shocks, long-term freezing of gears, emergency mode of the automatic transmission, the presence of critical errors in the automatic transmission in order to eliminate them, this most likely will not help you, opening, troubleshooting and repair are necessary.
2. If your car has a mileage well over 200,000 km, and you suspect (don’t know) that the fluid in the automatic transmission has never been changed, and it already contains strong impurities (cloudy) of wear products, then a replacement is unlikely to be useful to you. In more detail, with such a mileage without changing the fluid, wear products gradually accumulate in the automatic transmission, one might even say they are deposited in different parts of the transmission, then when changing the ATF, the new fluid, with the help of detergent additives in its composition, cleans the box of wear products, which can certainly get anywhere , make the automatic transmission work with kicks, jerks, due to loss/change of pressure, this will manifest itself more clearly in automatic transmissions that are already on the way to inevitable death. The change only reveals existing faults faster and more characteristically. It is in such cases that people, from hearsay, like a damaged phone, convey the tale that “replacing ATF 146% kills the box, do not change it under any circumstances!!!”
Of course, with a working box, maybe everything will work out, but no master will give you a guarantee for high mileage, it’s up to you to decide!

3. If the car's mileage is not huge, the fluid is relatively transparent, the gearbox behaves normally, then regularly replacing the fluid in the automatic transmission will only prolong its life. Of course, having forgotten to replace the fluid, if the box is not forced, it is unlikely to grunt at 150-200 thousand, but here there is already a question about the attitude towards the car. So again, it’s up to you to decide, but it definitely won’t make things worse.

Boxed liquid options

The clownery with ATF fluids that was staged at Audi in 2008 led to the fact that in any oil store, any salesperson who has not delved into the oil woes of the “rings” will definitely tell you that the only fluid that is poured into your automatic transmission is green under number G 060162A2. OD also, of course. Well, after replacement, you need to reload the software into the control unit of your automatic transmission, since the properties of the fluid have changed.
The catch is that Audi simply removed the old ATF from the catalogues, leaving only the green one and increasing its price by more than 2 times. But still, the inquisitive minds of Russian audio drivers dug up old catalog numbers in the annals!
Yellow G 055005A2, it is also an analogue of the original, which was actually poured for the plant - ATF Shell M1375.4
Blue (blue) ATF - G 055162A2, it is also an analogue of the original, which was actually poured for the plant - ATF Shell M1375.6

2. Introduction of optimized ATF (green) from March 2008
(Gearbox numbers: A4, A6, A8: 4432890, Q7: 4040037)

Solution in terms of service
Case A: Cars BEFORE 1st implementation:
To implement the service solution, it is necessary for vehicles up to model year 05 inclusive (implementation from gearbox numbers A: 4000597, B: 95253) to update the software of the gearbox control unit.

∙
The use of a new ATF requires the use of the appropriate software version. If there is no compliance, the consequence will be permanent damage to the gearbox!!!
1. Update the software in the gearbox control unit to the latest version (see the table at the link for original parts)
2. ATF, 2-stage replacement (1 x flushing and 1 x replacement). Only use fluid specification G 060 162 A...” This new ATF is green.
3. When updating the software, all setting values ​​of the switching elements in the gearbox control unit will be deleted. A final adaptation drive is required to ensure good gear shift quality in the box.

Case B: Cars AFTER 1st implementation:
After implementation, cars contain an optimized working fluid in the automatic transmission and a corresponding software version in the gearbox.
1. ATF, 2-stage replacement (1 x flushing and 1 x replacement). Only use fluid specification G 060 162 A...” This new ATF is green.
2. Delete the settings of the switching elements in the gearbox control unit. A final adaptation drive is required to ensure good gear shift quality in the box.
NOTE: For vehicles with MG06, you can erase the settings and carry out an adaptation trip with the launch of Guided functions!

If replacing the ATF does not produce results, submit a technical repair request.
Instructions for replacing ATF:
In order to remove residual old oil from the gearbox (for example, from the torque converter), it is necessary to carry out the flushing process described below.
1. Drain the ATF and fill in with new ATF (green, G 060 162 A...), check the ATF level in accordance with the Repair Manual and adjust.

∙
Before a car with air suspension is placed on a lift, that is, all 4 wheels are suspended in the air, it is necessary to activate the mode of being on a lift.

∙
Raise the car approximately 10 - 20 cm.

∙
All four wheels stopped touching the ground.

∙
Check the lift feet and fix them if necessary.

∙
Check the stability of the vehicle against rollover.

∙
Follow safety rules exactly
Local regulations and health and safety directives must be observed under all conditions!

∙
Under no circumstances should you start the engine or tow the vehicle without ATF!

∙
ATTENTION! Do not exceed the speed limit of 50 km/h according to the speedometer.
2. Observe the gear indication in the instrument cluster, start the engine and release the parking brake.
3. With the service brake on, set the selector lever to position D and carefully press the accelerator pedal.
4. In position D, carefully accelerate the transmission to a maximum speed of 50 km/h. Maintain this speed for a few seconds.
5. Carefully press the brake pedal and brake the wheels to a speed of 0 km/h.
6. Switch the selector to position "R". Lightly press the gas pedal to accelerate the rotation of the wheels to 20 km/h. Maintain this speed for several seconds.
7. Carefully press the brake pedal and brake the wheels to a speed of 0 km/h.
8. Move the selector lever back to position “D” and repeat steps 3 to 7 five times.
9. Then, with the wheels not rotating, switch the selector to position “P” and turn off the engine.
10. Drain the ATF and fill in with new ATF (green, G 060 162 A...), check the ATF level in accordance with the Repair Manual and adjust.

Instructions for the adaptation trip:
For vehicles with MG06, it is possible to erase the setting values ​​and carry out an adaptation trip after starting the Guided functions!
For older vehicles, proceed as follows:
1. Make a preliminary drive to warm up the ATF to a temperature > 60°C (ATF temperature should not be > 100°C).
2. With the car stationary, the engine idling and the brake pedal pressed, move the selector from N to D and maintain this mode for about 3 seconds. Repeat the process five times. After this, perform the same actions, moving the selector from N to R.
3. Drive the car so that it switches from 1st to 2nd gear with minimal pressure on the gas pedal, and then switches back 2-1. Repeat the process five times.
4. Drive with a light load (engine torque between 80 Nm and 100 Nm, see 02 Automatic transmission, measured value block 09, 1st display value) until the automatic transmission shifts to 6th gear (vehicle speed approx. 80 - 100 km/h) and maintain this mode for approximately 30-60 seconds. Release the gas pedal so that the car coasts (coasts) until it comes to a complete stop (at the end, press the brake very gently). Repeat this cycle four times (the point is to allow the automatic transmission to shift up and down with minimal load).

∙
After replacing the ATF, in isolated cases, extraneous noise may appear during the first 500-1000 km. Only if the phenomenon does not disappear even after the above mileage, make a technical request for repairs.

What should I change it to?

1. If your car has automatic transmission firmware for green fluid and you have no doubt that the name is filled there, then your car is most likely manufactured after 03/2008, or it was already changed there before you, then feel free to change the oil to G 060162A2, without flashing anything. Also, information about what kind of oil was poured into your automatic transmission on the conveyor can be found out by looking at the number on the nameplate located on the automatic transmission, or through a cord in the automatic transmission control unit, such as: Serial number: 4320826, then comparing it with the table in ETKA.

There is a high-quality substitute for this original liquid - this is liquid from ZF Lifeguard 8 of different volumes.

2. If, according to the nameplate, you have yellow or blue fluid, then you can also change it to green, as the dealer recommends, but this is more expensive due to the inevitable firmware of the automatic transmission ECU and an adaptation trip, although they say that this changes the behavior boxes are for the better, which is logical, new versions are written with the aim of eliminating shortcomings in the old algorithms of the boxes. But if you want to save money, you can change the fluid to Shell M1375.4, since it does not require any firmware changes after the change.
True, based on the “SO ST Special course on service technology” 03.2007, M1375.4 is the old yellow ATF, but, apparently due to the lack of M1375.6, many people change to M1375.4, although it is not easy to find in Moscow , and even then only on tap, as it is supplied in 208 liter barrels.
G 055162A2 is still available in many stores, but today its price tag is not much cheaper than green ATF.
There is another good substitute from the manufacturer ZF Lifeguard 6.

And another important note!
To find out what kind of oil was filled at the factory, it is enough to know the number of the automatic transmission control unit and the firmware number

To find out the number and letter code of the automatic transmission, you will need to get to the plate on the automatic transmission itself.

Audi A6 is a fairly common model in our country. It has proven itself well among car enthusiasts. But this car was created, and rules for its operation were developed without taking into account our climatic conditions and difficult roads. In this regard, car owners should slightly change the rules for maintaining the Audi A6. This rule also applies to the operation of an automatic transmission. It should be noted that since 2004, the Audi A6 C5 has been equipped with a new automatic transmission option. This modification is distinguished by its reliability in operation. If a breakdown does occur, then in most cases it is a leaking oil pump or a failure of the torque converter. The manufacturers of this car recommend not to produce the Audi A6 C5. It is intended for the entire service life of the automatic transmission. But almost any car owner will want to extend the life of this unit. This is quite possible through a complete or partial change of the transmission fluid.

The oil in the Audi A6 automatic transmission should be changed at the first malfunction of the gearbox.

When do you need to change the transmission oil in an automatic transmission?

• severe weather conditions with sudden and severe temperature changes;
• driving on poorly paved roads;
• frequent exposure to traffic jams;
• poor quality lubricant.

The first signs of loss of transmission fluid properties are the following:

• the appearance of jerks or jolts when moving from one speed to another;
• presence of increased noise in the automatic transmission;
• the car moves harder uphill;
• Gasoline consumption clearly increases.

Monitoring oil condition and level

If changes occur in the operation of the automatic transmission, you should first check the oil level and its condition. The lubricating fluid level is measured using a dipstick. In this car model, you can see several divisions on the dipstick. The lowest division shows us the oil level when it is cold, and the upper division shows us after the car has warmed up. We are interested in the second option. If the transmission fluid is above or below the optimal level, then perhaps this is the reason for the incorrect operation of the automatic transmission. Unfortunately, if this fact is ignored, a lack or excess of lubricant can lead to serious damage to the automatic transmission.

If the transmission oil level is normal, then it becomes necessary to check the condition of the lubricant itself. To do this, you need to take out the dipstick to measure the fluid level in the automatic transmission and drop a few drops onto a clean napkin. If the oil has a very dark or black color and, in addition, it has a burning smell, then it must be replaced as quickly as possible.

Automatic transmission oil Audi A6

Audi A6 C5 manufacturers strongly recommend using only proven manufacturers Esso ATF 71141 and Mobil ATF71141. More accurate data on the use of oils for automatic transmissions of the Audi A6 C5 can be found in the technical vehicle documentation or at the dealership.

It is worth considering that only original green fluid under number G 060162A2 can be used in automatic transmissions for Audi A6 C6 after 2008. To partially replace the lubricant when pouring into an automatic transmission, 5 to 7 liters are usually required. How much oil to add will depend on how much liquid can be drained.

Preparing to change the transmission fluid in the box

Before proceeding directly, you need to prepare:

• 5 – 7 liters of gear oil;
• a set of keys;
• cleaner;
• rags;
• pallet gasket;
• container for collecting drained liquid;
• bent tube for filling;
• new oil filter (if necessary);
• drain and fill plugs (if necessary);
• new bolts for the pallet (if necessary).

Change of oil

Before starting, the transmission fluid in the automatic transmission should be warmed up to approximately 70 - 80 degrees. This will speed up the draining process.

Partial oil changes are a fairly lengthy process, but if this procedure is carried out regularly, you can not only significantly improve the performance of the automatic transmission, but also extend its service life by almost half.
